Essay Questions Answer
- What is randomization and the benefit of it?
Randomization is the process of choosing the samples from a population randomly, giving everyone equal chance of being selected. It makes all participants experience the same conditions in the study except for the difference in interventions they receive. Randomization enables the researchers to perform blinding and randomization when choosing the sample and compare the control group with other experimental group/groups. As a result, the cause and effect regarding the intervention and consequences involved is proven with high internal validity.
